[Rd] write.table row.names and col.names (PR#2610)

[Warnes, Gregory R]

>From ?write.table:

     Normally there is no column name for a column of row names.  If
     `col.names=NA' a blank column name is added.  This can be used to
     write CSV files for input to spreadsheets.

> When data.frames are written to a file using write.table and 
> with row.names and
> col.names, then the colnames are displaced by 1 with respect 
> to column content.
> Example:
> 
> 
> > x = data.frame(
> >   obscht=c("chriesi", "bire"),
> >     gmues=c("chrut","hoerdoepfl"))
> > rownames(x) = c("huet", "morn")
> > write.table(x, file="test.txt", sep="\t", quote=F)
> 
> The table x now looks like:
> > x
>       obscht      gmues
> huet chriesi      chrut
> morn    bire hoerdoepfl
> 
> but the file is as follows, and the column names will be 
> confused when reading
> this file e.g. from Excel.
> 
> obscht	gmues
> huet	chriesi	chrut
> morn	bire	hoerdoepfl
